Thank you for your response. Unfortunately, the update did not solve my issue. I pulled the latest git repo, rebuilt the demo application, and still get the same error message....

Any new information?

Thank you for trying to help me work through this issue. I tried both configuration files. Neither succeeded in initialising the sensor in Linux. Both worked in Windows, however. I...

I will try the 8bit mode configuration with the USB2 revision of the ArduCam and see if I can get a framerate acceptable for my application, since the USB2 revision...

I'm afraid I am seeing the same result with the most recent configuration. I am connecting the ArduCam to a USB3.0 port (not a hub). The OS detects it as...

> @joncppl The link you provided is to the `rclcpp::ClientBase::wait_for_nanoseconds` method, which as far as I can tell is never invoked during `rclcpp_action::ActionClient::wait_for_action_server_nanoseconds`. Or am I missing something? > >...

I believe the reason the example works is because rclcpp::ok falls back to default context since pimpl->context is null, so this condition is true despite the null context. However my...

This issue can occur at runtime when action servers disappear/restart/etc. I believe the KeyboardInterrupt/shutdown considerations are a red herring and there is an underlying bug in foxy. I propose patch...
